fix: resolve remaining CI failures

- Fix Map type annotation in store.js (TS error)
- getMaskConfig falls back to global.maskSensitiveData for unit tests
- Update ui_test.js to check store.featureOnly instead of process.env
- Remove Object.defineProperty freeze on paths — causes issues when
  unit tests share process and shard_test calls initialize() first
- Restore process.env.RUNS_WITH_WORKERS for cross-process communication
  (env vars cross process boundaries, store doesn't)
